-# Using the Edge Connector
+## Accessory list
 
-The micro:bit card edge connector, commonly referred to as the 'edge connector' or the pins is designed to make accessory design easy. Many common micro:bit accessories work by placing a female edge connector on the board. However, there are limitations to the current that can be drawn from the micro:bit, and accessories must be designed carefully to ensure they do not damage the micro:bit, or that the micro:bit cannot damage them.
+A [list of available accessories](https://microbit.org/buy/accessories/) is maintained on the micro:bit website.

+### V2 revision
+The edge connector on the <span class="V2">V2</span> board revision is backwards compatible with the <span class="v1">v1</span> edge connector, but has additional dedicated pins.

-# Battery Pads
+## Battery Pads
 
 There are two lozenge shaped pads on the back of the micro:bit. These allow you to connect a battery holder via a mechanism other than the JST connector.
 
+
 ![Picture of the two lozenges](/docs/accessories/assets/making-accessories-d7c25.png)
 
+### V2 revision
+In the <span class="v2">V2</span> board revision, the 3V lozenge is connected to the 3V ring on the edge connector.
+
+- If you make an accessory that uses the lozenges, it must be protected from reverse charging
+when the board is powered by USB, battery or edge connector.
+- You can now source power from the lozenges if you are making an accessory, as they are consistent with the power architecture of the edge connector.
+
+Due to the addition of a speaker, current accessories that use the lozenges to power the micro:bit will no longer fit.
